My Vultr Server Just stoppped Working

I’m using vultr server and my WordPress website was hosted over there… I got a database connectivity issue… which shouldn’t have happened as I was not using the website and no one else does.

Then I restarted the server. Now the website does not load it.
I’m using the LEMP method to host the website.

Now i want to get back the website online.

I’m getting 521 Hosting error. I tried it with ip address but no luck.

@GulshanKumar I think there might be a problem with Apache or PHP?

First off, do you have Backup?

I don’t have the backup but the data is on server!!!

I think mysql is killed/not running… (could be due to low RAM) try to run/start mysql.

I got an database error ! Then I just restarted my server!

Oh sorry to know about that.

This will require extensive debugging. I would suggest hiring this person to get fixed.
